DUMPING-WAGQN.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed May 9, 1908. Serial No. 431,748. A

T 0 all whom it may concern:

Be it known that 1, CHARLES HEINLEY, a citizen of the United States, anda resident of Amityville, in the county of Suffolk and State of NewYork, have invented certain new and useful Improvements in DumpingWagons, of which the following is a specification.

My invention relates to dumping wagons designed to carry and delivermaterial such as coal and the like; and particularly to wagons of thischaracter in which the material carried is quickly-emptied by raisingone end of the wagon body and permitting the material to run out theother end through a suitable chute or the like. I

It has for its object the more ready and simple dumping of the load.

For this purpose my invention consists of certain novel features ofconstruction which enable the load to be swung at any suitable anglehorizontally as well *as allowing the load to be raised at one endaccording to the usual practice.

In the accompanying drawings which illustrate my inventionFigure 1 is aside elevation of my improved wagon, and shows also the wagon body (indotted lines) in the raised position. Fig. 2 is a plan view of the wagonwith the wagon body removed, showing a rotatable support for said wagonbody; and also (in dotted lines) said support swung in a horizontalplane. Fig. 3 is a rear elevation of my improved wagon. Figs. 4 to 8 aredetail views on an enlarged scale of'the guiding arrangement for holdingthe wagon body in position when raised and lowered. Figs. 9 and 10 arerespectively front and side elevations on an enlarged scale of theraising mechanism. Fig. 11 is a partial side elevation on an enlargedscale of the raising mechanism showing the same in unlocked position topermit the wagon body to descend.

Similar characters of reference designate corresponding parts throughoutthe several views.

Referring to the drawings, 20 designates the wheels of a dumping wagonsuch as used to convey coal and the like. These wheels carry a frame 21uponwhich are two-stringers 22, one at each side and approaching eachother toward the front of the wagon. These stringers carry a frontbolster 23 and a rear bolster 24 forming'with the stringers a stationaryframe normally supporting the wagon body 25, said body resting in thebolsters 23 and 24 through front and rear supports 26 and 27respectively, projecting from said body. The forward support 26 isprovided at its lower extremity with an inverted channel shaped piece 28adapted to straddle the bolster 23, resting upon a metal piece 29secured thereto. provided with an extension 30 adapted to fit the dishedportion 31 of the bolster 24. By these means the body 25 readily andquickly locates itself with respect to the frame 21 and further, islocked, in this its normal position, against displacement horizontally,but is perfectly free to move vertically. Means are provided at the rearof the wagon body whereby the said wagon body may be raised to assume aninclined position as indicated in dotted lines, (Fig. 1). This mechanismwill be hereinafter fully described.

Mounted upon the stringers 22 and crossbeams 22 is a metallic ring 33.This ring supports, as hereinafter described, a rotatable, annularguide-way 32 which is designed to carry cross-pieces 35, which in turncarry on each side of the wagon the frame pieces 37 of a second andmovable frame. The said guide-way 32 carries between its walls a numberof rollers 33 which rest upon the said ring 33, the guide-way being freeto turn upon said ring and the rollers 33 providing a roller bearing orsupport for same. Upon the top of the rollers 33 is placed a ring ortable 34 which carries the cross-pieces 35. An annular angle piece 36fits over the top of the ring 34 as well as the outer wall of theguideway 32, aflording a cap to prevent the entrance of dust, smallpieces of coal or other objectionable material to the said guide-way. Atthe forward end of these frame pieces is secured an angle piece 38having a hole 39 adapted to receive a piece 40 secured to the wagon body25. The rear ends of these frame pieces 37 carry the raising mechanism,shown on an enlarged scale in Figs. 9 to 11.

As shown in Figs. 9 to 11, a rack 41 is pivotally secured at its upperend to the side of the wagon body 25, one rack being attached to eachside (Figs. 2 and 3). These racks engage with respective pinions 42 ro-The rear support 27 is tated by a shaft 43 mounted to turn in bearings44 pivotally secured to the frame pieces 37. A ratchet 45 is mounted onthe shaft 43 and operates to turn said shaft through the action of apawl 46, controlled by an arm 47 and held in engagement with the ratchet45 through the action of a spring 48. In raising the arm 47, which-isloosely mounted on the shaft 43 the pawl slips freely over the teeth ofthe ratchet and the said shaft isnot turned. "When the arm 47 is pulleddownwardly, the pawl 46 engages the teeth of said ratchet whichtherebycauses the-same to turn, .and with it the shaft 43. This rotatesthe pinions 42 which in turn raise the racks 41 and therebythe Wagonbody.25. For small loads, viz. up to 2 tons, I prefer to use this meansof raising the wagon body, as it is much faster; for heavier :loads, itis advisable to employ the usual and well knowncrank system, whichhowever is. considerable slower.

In lifting the wagon body 2'5or the load, the arm 47 is raised to abouttheposition shown in dotted lines .Fig. :10 andthertpulled downwardly asexplained; and this is repeated untilthe load is liftedithedesiredamount. The ratchet 45 is held during the return of the pawl 46by alocking pawl 49 engaging said ratchet and pivotally connected to thebearing 44, and held in locking engagement through the action of :itsweighted end 50. To lower the wagon body, the arm is aaised to about theposition shownin Fig. 11, the arm 51 having been previously turned byhand tolthrow the pawl 46 out of engagement with its ratchet 45. In thislatter position the pawl 46 throws the locking pawl 49 also out ofengagement with ratchet 45,.and both pawls thus being free and clear ofthe said ratchet, allow the same to return anddrop the wagon body 25 to.its normal position, Fig. 1.

So soon as the wagon body 25 is raised, it is lifted off the bolsters23-and 24 upon which it normally rests, and is carried by the framepieces 37, which in turn are carried by the rotatable table 34, thefront of said wagon body being carried by the pieces 40 turning in theholes 39 of the angle pieces 38. So soon as the load is thrownoff thebolsters and is carried by the table 34, it :may be swung horizontallyto any desired position convenient for .unloading, the table 34 turningfreely on the J'I'OIIGI'S 33. ii hen the wagon body againdescendsitonormal position, the table is relieved ofthe load which is again takenby the bolsters 23 .and 24, the body 25 readily and quickly locating andlocking itself as explained.

,"Vhile I have shown'the wagoniconstructed with a specific form offrame, yet I do not wish to restrict myself to the particular frameillustrated, as my invention may :be applied to other styles of wagonssuch, for example, as the platform spring wagons.
